Brake unit (FR-BU2 type)
When running the motor with the FR series inverter, use this option unit
when a large brake torque is necessary such as when the motor is made to
run by the load, quick decerelation is required, etc.
Following three types of brake resistor as in the table below can be
connected to this option unit. FR-BU2 type break unit can be used as
substitute of the existing brake units (BU type, FR-BU-(H) type, MT-BU5
type).
Do not operate the conventional brake unit and FR-BU2 in parallel. Doing so
could cause an alarm or failure. Change all units to the FR-BU2 to operate in
parallel and connect the master/slave signal.
Perform wiring and parameter setting referring to
page 15
as the wiring
method and parameter setting method differ according to the brake resistor
combined.
